Cleveland Cobalt End Mill 3/8" 4-Flute

The Cleveland Golf end mill is a cobalt square-end cutter with a 3/8 inch diameter and four flutes. It is designed for general-purpose milling in ferrous and non-ferrous materials where cobalt offers improved heat resistance over high-speed steel. The centre-cutting geometry allows the tool to plunge directly into the workpiece. Overall length is 2-1/2 inches.

Machinists needing a versatile centre-cutting

This tool suits machinists and fabricators who require a single end mill for slotting, profiling and plunge cuts in steel or alloys. It is not suited for high-volume production runs where solid carbide tool life justifies the higher cost. Buyers needing ball-nose profiles for 3D contouring or a larger diameter for heavy material removal should select a different geometry.

3/8 inch diameter with centre-cutting four-flute

The 3/8 inch cutting diameter combined with four flutes and centre-cutting capability determines the tool's rigidity, chip clearance and ability to start a cut without a pre-drilled hole. This specification decides whether the cutter fits the required feature size and milling strategy for the job.

Questions about this item

Does the 3/8 inch shank fit a standard 3/8 inch collet or end mill holder?

Yes, the 3/8 inch diameter shank is made for standard 3/8 inch collets, Weldon flats, or side-lock holders; match the holder bore exactly to avoid run-out.

What machine clearance is needed for the 2-1/2 inch overall length?

The tool measures 2-1/2 inches overall, so the spindle-to-workpiece gap must exceed that length plus the depth of cut; verify Z-travel and fixture height before machining.

How should this cobalt end mill be secured to prevent the flutes from being damaged during tool changes?

Clamp only on the smooth shank — never on the fluted cutting section — and tighten the holder evenly to avoid cracking the cobalt substrate.
